Abstract: A grip assist device configured to be securely adhered to and removed from a grip bar of an athletic training weight. The grip assist device has a flexible grip wrap that can be attached to and detached from the grip bar. The grip wrap has a plurality of peaks and finger depressions on its exterior surface, a non-slip feature on its interior surface, and one or more sensors that can sense various forces on and motions of the gripper to provide useful feedback information to a user during a training session with the training weight. The sensor(s) can pair with a computer software application that analyzes the data sent from the sensor and provides one or more direct and/or derived measurements from the torque and/or range-of-motion measurements to the user.

Abstract: An alignment device for a weapon that generates a simulation beam and an alignment beam used to align the simulation beam with the weapon's sight. The device can be secured to the weapon during the alignment process, after which it can be removed. The device includes a housing that can be mounted on the weapon so that its optical receiving port intersects both the optical alignment beam generated by the optical transmitter and the sighting axis of the weapon's sight. The optical receiving port includes an optical arrangement for receiving the alignment beam and focusing it on a projection screen located inside the housing. An image of the alignment beam on the projection screen can be viewed through the sight. The alignment beam is parallel to the simulation beam. Thus, by centering the alignment beam in the sight, the alignment beam, and hence the simulation beam, will be properly aligned.
